In many metastasized types of cancer, disseminated tumors grow back despite successful chemotherapy.
Researchers from The University of Bern, Switzerland, has now discovered, this is because of isolated cancer cells that survive the chemotherapy due to a phase of dormancy.
If these "sleeper cells" possess specific defects, however, they can be destroyed.
This could increase the efficacy of chemotherapy for certain patients.
The study was published in the Clinical Cancer Research journal.
